Hmm, no newline at the end of the output? Haven't tried my hand at this one but it looks really easy so if I get around to it (working on a few others at the moment), I'll let you know.
BTW, it *might* be throwing garbage in the input, which you should ignore. ie, "this\t\is" should return:
t
h
i
s
i
s
and not:
t
h
i
\t
is
I've only done about 20 since the 23rd of July, and every time I get PE it's something silly with the input/output, garbage text or something unexpected in the input. They like to trick you up.

edit: trailing spaces are "okay" (and possibly expected), haven't tried writing a "strip trailing spaces" function, but I might if I get bored.
This was a cool and easy problem.

Erm. Screw all that crap I was writing. I got AC, the problem is that it expects a newline at the end of the output! Grr! I would've got it on my first try had I done that.
I hate this! Die PE die!

i tried all the combinations of a blank line:
* at the beginning of the first output
* at the end of the last output
* both at the beginning and at the end of the output
all i got is a PE!
ps: TABS (\t) are not legal characters for this problem.

even i am getting PE....although my code do not output space at the end..something else is amiss..
Code: Select all
#include<iostream>
#include<string>
#include<vector>
using namespace std;
int main()
{
vector<string> v;
string s;
vector<int> vi;
while (getline(cin,s))
{
v.push_back(s);
}
int m=0;
for (int i=0;i<v.size();i++)
{
vi.push_back(v[i].size());
if(v[i].size()>m)
m=v[i].size();
}
int c=0;
while (c<m)
{
for (int i=v.size()-1;i>=0;i--)
{
if(vi[i]>c)
cout<<v[i][c];
}
if(c!=m-1)
cout<<endl;
c++;
}
return 0;
}
help...

Do you or do you not have trailing spaces? My output does, and I got AC. Do a forum search for this problem, there are some sample data to try.

It needs trailing spaces as far as I understand.

got accepted. the judge was looking for trailling spaces as well as a newline at the end of the output.

Can someone tell me, what's wrong with my code?

I think that you didnt read the problem well.
try this input:
Code: Select all
amen!
CCCCCCC
BBBB
AAAAAA
DD
E
"Mike"
The output of the program should have the last sentence printed out vertically in the leftmost column; the first sentence of the input would subsequently end up at the rightmost column.
can you figure out whats wrong in your program ?

I tried that input and my code produce:
Code: Select all
"EDABCa
M DABCm
i ABCe
k ABCn
e A C!
" A C
C
Thank you mogers, but I think my output is correct.
I just enlarge the size of array and post again that code.
And suprisely, I got AC.
GOT PE
